Here is a new version of the trigger guard rivet jig. The rear is adjustable for use with receivers with original rivet spacing plus with Tapco flats. On the front side of the jig there are slots for the mag catch rivet to clear. Once that's done a small c-clamp is used to set the spacing on the front rivets.
He will no longer be making two different versions of rivet head size supports on these jigs. Be sure to buy the right rivets either from me or where other real AK rivets are sold.
These are manufactured by AK-47 Builder.
